Compared with prior art, the beneficial effects of the invention are as follows：The present invention is that one kind can realize two kinds of pavings of J-type and reel
If integrated pipe laying system, by being integrated to related installation apparatus, sizes under the various depth of waters can be completed, many
Material, multiple diameter pipe laying work are planted, equipment can not only be reduced and use total amount, and can need to fit according to actual laying
When switch paving mode, reducing suffered by pipeline in the case of stress, improving pipe laying quality and efficiency, improving economy, tool
There is very strong synthetic job ability.
Generally according to exploitation oil gas actual conditions, it is necessary to polytype, multiple use, multiple diameter pipeline be laid, by J-type
It is rationally integrated with two kinds of pipe laying modes of reel, it can not only retain respective paving mode advantage, lack while making up single type
Point, improves compatibility and economy.
Break through single paving mode limitation：(a) polytype, purposes pipe laying work can be completed, not by pipeline material
Matter is limited, and can lay hard tube can lay flexible pipe and umbilical cables etc. again.Two kinds of paving modes are combined, are not increasing pipe laying barge number
Under amount and device category service condition, paving mode can be switched in good time as needed, it is ensured that laying efficiency simultaneously, improves economical
Property, save installation cost；(b) different size pipe laying work can be completed, are not limited by diameter, while as needed in good time
Switch paving mode, improve economy.It is 2 inches to 18 inch conduits to lay diameter range, is saved using pipe crimping paving mode
Cost；18 inches of diameter range is laid to 32 inch conduits, installation quality is ensured using J-type paving mode；(c) it is not only suitable for shallow
Water operation, is also applied for deep water and ultra-deep-water operation, breaches single paving mode and is limited by the depth of water and economy.By two kinds
Paving mode is combined, when the depth of water changes with laying length residing for the pipeline of laying, it may be desired to switch paving mode (J-type in good time
Laying considers from economy point, is mainly adapted to deep water and ultra-deep-water operation, and reel laying considers from economy point, mainly
Suitable for shallow water), operating efficiency is improved, installation cost is saved.
Optimize single paving mode transaction capabilities：(a) reel laying Pipe installing quality and efficiency are improved.Pipeline is from reel
During upper debatching, pipeline remains tangent state with laying tower decentralization path, and aligns direction for vertical direction, is in gravity
On same position, aligning efficiency is improved, while avoid pipeline section from aligning generation circumferential deformation on conventional bevel direction,
Reduce influence of the bending to ultimate strength and fatigue behaviour；(b) equipment integration is carried out, equipment is reduced and uses total amount (such as stern support
Pipe support etc.), saving equipment, which is individually arranged, to be taken up space；(c) reel is arranged vertically, mobility strong, and laying speed is fast；(d) tension force
It is more prone to control.No matter using J-type laying or reel laying, equal over entry when pipeline departs from pipe laying barge, press close to " from
So " state, in linear elastic range, reduces the free span of pipeline, is welded than the overwhelming majority of S-shaped state stress small (e) under water
Connecing work can complete in the controllable environment of land workshop, it is ensured that welding quality.
Improve pipe laying speed.(a) when J-type is laid, centering and preheating about need 2 minutes, pipeline welding before pipeline welding
Time is about needed 12 minutes, and Non-Destructive Testing is about needed 5 minutes, and application is about needed 3 minutes, and elevator lowering velocity is about 12.2m/min.Therefore
When the designed integrated paving system of four nodes is laid using J-type, theory laying speed is：
24 × 60 ÷ { (2+12+5+3)+(12.2 × 4 ÷ 12.2) } × 12.2 × 4=2702.8m/d
Speed 1.5km/d improved efficiencies 80.2% are laid compared to typical J-type
(b) laid using reel, pipeline can continuous laying, the marine laying time is short, it is ensured that the rapidity of pipe laying,
Lay advantage of lower cost.Typical reel laying speed may be up to 1 km hour, average about 600 meters per hours, compared to typical J-type
Lay speed 1.5km/d improved efficiencies 860%
Deethanizer design height 52m is laid, tower height is relatively small, under the premise of laying efficiency is ensured, improve stability, reduction is made
Industry risk.Laying tower height degree is general in 80-135m on pipe laying barge in current engineering, compared to reduction more than 35%.
Pipeline is directly promoted to installation tower top layer by loading arm, is removed pipeline lift facility from, is reduced during pipe not
Necessary process, makes the transmission of pipeline section simple and easy to apply.It is cost-effective, mitigate weight, improve operating efficiency.Laying tower angle can be achieved
Degree is smoothly adjusted between 70 ° to 110 °, can meet the laying requirement of different water depth and caliber, reduce pipeline section top by
Power.Welder is arranged in same working position with the cannot-harm-detection device, if welding detection is off quality, can in time handle, subtract
Few unnecessary process, it is to avoid influence laying efficiency.Do not move pipeline welding, detection and coating procedure, position, it is ensured that installation quality
Meet index.In laying bottom of towe end increase suspension platform, the installation of the key equipments such as PLET, PLEM is realized, it is ensured that laying operation
Laying efficiency is also improved while security.
